DYE-BECK.

Application filed July 20, 1916.

To all whom t may concern Be it known that I, CAY BUI-IL, a subject of the King of Denmark, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Dye Becks, of which the following isa specification.

This invention relates to dyeing machines of the class known as dye-becks, in which the fabric or fabrics to be treated are caused to travel lengthwise through a vat containing the dyeing or other liquid by means of a rotary member or members around which the fabric extends and by which it is advanced due to frictional contact therewith, the fabric or :fabrics usually having their ends temporarily secured together so as to make of each an endless band or belt that Vin the treatment repeatedly passes through the liquid in the vat.

ln these machines means are usually provided for imparting to the part of each fabric which extends downwardly from the said advancing means (usually placed above the liquid) upon delivery therefrom aback and forth movement so as to arrange the fabric in a series of back and forth folds, thus to produce an orderly pile of the fabric and avoid thereby its bunching or becoming snarled or entangled in the liquid. The present invention consists in certain improvements in the means for imparting such movements to the fabric, the same having for their principal objects to make the mechanism more compact and simpley and insure a more regular and even disposition of the folds of the fabric pile.

In the accompanying drawings,

Figure l is a side elevation of a dye-beck having my improvements; and,

Fig. 2 is a left hand elevation thereof.

`On a suitable supporting structure including the vat a for the dyeing or other liquid and a frame b upstanding therefrom are journaled on horizontal axes the rotary drum c and beam cl, connected by a sprocketand-chain means e whereby rotary motion applied to the beam is transmitted to the drum.

The power for rotating the beam is derived from the motor f, suitably supported on the frame o, through a sprocket-andchain connection g and a clutch-device which Vincludes the clutch-member It, rotatable on the shaft el', of the beam and constituting Specification of Letters Patent.

one element of the sprocket-and-chain connection g, and the clutch-member z', splined on said shaft. The latter clutch member is adapted to be shifted outwardly to open the clutch and cut the beam off from the power by automatic means including the rake g pivoted in the frame Z) and connected by the flexible device y', (extending around the pulley 7;) with the lever Z engaged with clutch-member z' in a well-known manner. The manner of operation of this means will be explained hereinafter.

The fabrics to be treated, each having its ends secured together by stitching or otherwise so as Ato give it the form of a belt, extend around the drum and beam as shown in Fig. l, and they are adapted to be arranged in successive folds to form even and regular piles at `the left-hand end of the vat as they are advanced through the liquid due to frictional contact with the drum and beam (rotating` in the direction of the arrows in Fig. il) by the following novel means:

A horizontal shaft m is journaled in the frame 7) above the vat, carrying at its ends T-heads a in which are arranged the arms o, the major portion of the length of which extends downwardly. The said arms may carry above the shaft m the weights 7?.

adjustable thereon. At its lower end eacharm'is equipped with a bracket g, the two brackets affording `journals for rollers r (having their axes parallel and horizontal) between which the fabrics extend on their way downwardly to enter the liquid after passing the drum. VDrum c and shaft fm, are respectively equipped with sprocketwheels s and t around which extends the endless chain u. Said shaft and the rollers o' are respectively equipped with sprocketwheels fr, 1.o and a: around which and an idler sprocket wheel .c journaled in one of the brackets f/ extends the endless chain j1,/, the disposition of which with reference to the sprocket-wheels 'w and a; is such that both stretches thereof are on the same side of the latter, whereby advance of the chain causes the rollers to turn in opposite directions. The chain y being caused to rotate in the direction of the arrow in Fig. l, the rollers of course rotate in a direction corresponding1 to the downward advance of the fabric.

The structure comprising shaft m, T-heads n and arms o and the parts carried thereby 4rics occurs. rotated, by the means described, in the direcis oscillated by a link or links z connecting the same with an eccentric portion of the drum, as shown in Fig. l.

As the fabrics are advanced by the drum and beam in the manner already stated the aforesaid structure is simultaneously oscillated. This causes the fabrics to lbe formed into back and forth folds in the manner shown in lT ig. l, at Al, but at the ybottom of the vat, producing piles from the bottoms of which resumption of advance of the fab- The rollers 7' 7" are positively tions of the adjoining arrows shown in F ig. l, thus to prevent the part of the fabric above them, more or less heavy with the liquor, from flapping over one or the other roller and so possibly discontinuing to advance. The sprocket t is sufficiently smaller' ,than sprocket s so that the surface speed of the rollers r r is greater than that of the fabric, thus to insure further the desired result of uninterrupted downward delivery.

The. machine is started by shifting the lever] to the position shown in Fig. Q, where the clutch is closed This makes taut the connection fj between the lever and the rake.7 The machine is manually stopped by shifting the lever revcrsely. Or stopping will be accomplished automatically, should a bunch or tangle of the fabrics engage the arms g of the rake, by pressure thereof against the rake, which willthen be shifted in a direction corresponding to the progress of the fabrics and so, through connection shift the lever.

The pile A is such as is formed, on the the removable platform of boards B, when the fabrics are to be removed from the machine, preparatory to which the stitching securing the ends of each fabric is cut so that the whole of each fabric may be arranged in a pile as the nal step in the operation.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is l. In an apparatus for treating fabric, the combination of a supporting means, rotary means to advance the fabric journaled in the supporting means on a horizontal axis, a swinging fabric-guiding structure pivoted in t-he supporting means on a horizontal axis, and a link connecting said structure with an eccentric part of the rotary advancing means.

2. In an apparatus for treating fabrics, the combination of a supporting means, rotary means to advance the fabric journaled in the supporting means on a horizontal axis, a swinging fabric guiding structure pivoted in the supportingmeans on a horizontal axis above t-he rotary means and having its fabric guiding portion below said rotary means, and a link connecting` said structure with an eccentric part of the rotary means.

3. In an apparatus for treating fabrics, the combination of a supporting means, rotary means to advance the fabric journaled inthe supporting means on a horizontal axis, a swinging fabric guiding structure pivoted in the supporting means on a horizontal axis above the rotary means and having its fabric guiding portion below said rotary means and co-nsisting ofa pair of o oacting fabric guiding rollers, a link connecting said structure with an eccentric part of the rotary means, and means to transmit rotary motion from said rotary means to the rollers.

In testimony whereof-I aflix my signature.
